Previously, users have used two workarounds as a temporary solution - “XP Fix” which uses Intel PRO Wireless 3945ABG driver designed for Windows XP, or rollback and switch back to Microsoft driver comes with Vista for Intel PRO Wireless 3945ABG network card. However, these workarounds have an drawback and disadvantage that the Wireless network or LAN is not optimized for fastest possible speed, instead opt for lower reliable speed throughput, and also have poor radio signal level problem.<br><br>Luckily, Dell has released a new updated driver supporting Intel PRO/Wireless 3945ABG Network Connection and Intel Wireless WiFi Link 4965AGN. The driver version 11.1.1.22 dated 08/08/2007 comes from provider Intel, is packaged as R164259 (11.1.1.3) - A05 - August 2007 release. It fixes the following bugs (changelog):<br><br> * Addresses 3945ABG radio disable seen with some systems running with Bluetooth modules<br> * Addresses 3945ABG radio disable seen in some 802.11a environments after Standby or Hibernate<br> * Addresses installer upgrade behavior where Windows Vista Preferred Networks would be lost<br> * Addresses installer interaction with InstallShield Update Manager causing an unwanted prompt during installation<br><br>The new driver will likely to solve the Wireless cuts off problem in Vista. Download the driver version 11.1.1.22 from [url=ftp://ftp.dell.com/network/R164259.EXE][b]ftp://ftp.dell.com/network/R164259.EXE[/b][/url]. It’s a Dell installer package, which should works on other brands too. Otherwise, simply extract the driver by using WinRAR and manually update the driver for the network card from Device Manager.<br><br>Post your outcome.

It would drop the connection to the Internet, then drop the connection to my Network/Router, then connect again after a few minutes but go agonizingly slow. Finally last weekend, it hardly connected at all despite repeated attempts to Repair Connection, Reset Adapter, get new IP Settings, etc. </P><P>Now that I've got it fixed, I wanted to put all the things I did into one post in case it helps someone else. </P><P>I sifted through at least a dozen websites and ultimately I tried 11 tweaks. It's now been 8 days without a single dropout, AND my connection speed is much faster. Here are the 11 things I gleaned from across many sites (including this one), in the hope that these help you. I won't describe exactly how to do each of these or why it *might* be important, because it's covered in lots of other posts here.</P><P>1) Change the channel on your router from 6 to 12. Ultimately, I think this was the most important thing for my situation.</P><P>2) In your Wireless Connection Network Properties, "Networking" tab, disable QoS Packet Scheduler. Don't need it.</P><P>3) In your Wireless Connection Network Properties, "Networking" tab, disable Internet Protocol Version 6 (IPv6). You <STRONG><U>must</U></STRONG> leave IPv4 enabled, you need this.</P><P>4) In your Wireless Connection Network Properties, "Networking" tab, disable both of the LinkLayer Topolgies. Don't need it.</P><P>5) Switch the power setting on your Wireless Adapter to "Max" or "Always On". Powering it up and down to save energy *might* cause connection problems.</P><P>6) Disable UPnP (Universal Plug and Play) on your router. This feature can be handy in some cases, but *might* cause connection problems.</P><P>7) Get the latest firmware from your router manufacturer's website, and install it. Some router manufacturers have updated their router firmware for Vista.</P><P>8) Enable "Broadcast my SSID" on your router. Some people think that unbroadcasted SSIDs don't connect properly in Vista. A diagnostic test on my machine flagged this too. It *might* cause connection problems.</P><P>9) Disable Wireless Security on your router. I've since turned this back on (WPA-TKIP) with no connection problems, and <STRONG><U>it's critical to turn this back on if you broadcast your SSID</U></STRONG>.</P><P>10) Turn off Windows Firewall. Some folks think the handling of packets by Windows Firewall (and other firewalls) *might* cause connection problems. I've since turned this back on just to be safe, even though I'm behind a router.</P><P>11) Turn your Wireless Adapter's romaing tendency to "conservative" or "minimum". Don't let it roam in "aggressive" or "maximum" or "seek best connection" mode.</P><P>I hope this post helps you, since it took me the better part of a day to sift many, many forum posts across multiple web sites to find all these possible fixes.</P><P>In case any MS staffers see this post and want to know my equipment: Dell Inspiron 530, Vista Home Premium, Core2Quad, 4GB RAM, with Broadcom 802.11g Network Adapter.</P><P>BTW, it's obvious after going through so many posts (including some posts where MS staffers were asking questions) that Microsoft knows this is widespread and doesn't know how to fix it yet. It's increasingly hard to believe they didn't see this problem before they released Vista.</P><P>Good luck!!!</P><P>Keywords to help others find this information when they search like I did:</P><P>Windows Vista Dropped Wireless Connection Network Won't Connect Slow Drop Internet ConnectednessSun, 24 Aug 2008 21:19:36 GMTdfamqwrkrtenhttp://www.vistaforums.com/Forum/Topic4198-45-1.aspxSo my girlfriends laptop has been having this same issue and to no avail could I find any information about it.

The problem appears to be dealt with for now. Monday night was a success without any annoying network problems. Thanks to the other posters here for helping me out with this by posting in this thread!!!!Wed, 04 Apr 2007 13:54:53 GMTmdesarnohttp://www.vistaforums.com/Forum/Topic4198-45-1.aspxcrap well the new intel drivers have fixed the greenbar problem but i still get drops although they are much rarer. p.s. I have had less drops using intels driver only rather then the intel driver+software thing.Tue, 03 Apr 2007 14:22:59 GMTJustSomeGuy1http://www.vistaforums.com/Forum/Topic4198-45-1.aspxI had a dropped connection about an hour and a half after my post, like usual. I left the computer on the rest of the night, but it was still connected when I got up in the morning. The real test will come on Monday, when I'm using the Internet with WoW and Ventrilo.Fri, 30 Mar 2007 12:30:25 GMTmdesarnohttp://www.vistaforums.com/Forum/Topic4198-45-1.aspxI've been having the same problems for the last several weeks. Every Monday night I play World of Warcraft on my Dell Inspiron E1705, using an Intel 3945 wifi through a D-Link DGL-4300 wireless router. I have been getting kicked off of my connection about once every hour to hour and a half each "game night" since I switched over to Vista. The problem is exactly like others mentioned, you can't get the connection back until you restart the machine, and even then it takes several agonizing minutes to reconnect. It's been driving me crazy and I want it fixed, I like Vista a lot and don't want to go back. <P>After reading this thread this week, I tried the following suggested changes:</P><P>1. Turned SPI off on the router</P><P>2. Downloaded the new Intel 3945 driver someone mentioned [actually tried to get XP drivers but Vista kept automatically loading other drivers, so gave up on that and used the new ones from Intel from a couple days ago].</P><P>I noticed immediately after #2 that my connection registers 5 of 5 signal strength bars. It never had more than 3 with any connection before. Weak connections [like the one I piggy back on from across the street at work] seem even more shaky than before, but are still usable. I left it on overnight on my home network last night and in the morning when I looked at it, the connection was dropped. Tonight I have made the following additional changes also per this thread:</P><P>1. I did some pinging with the following packet sizes: 1500, 1472 and 1432. I noticed no packet loss, but I did notice that the 1472 size ping had a much faster average speed. Don't know if it was coincidental or not and was too lazy to do more pinging to find out. Did not make any MTU changes yet.</P><P>2. Disabled the Teredo Pseudo-Tunneling Device in the Device Manager under Network Adapters [to see this, must check Show Hidden Devices up top under View in the Menu Bar].</P><P>3. In the properties for the wireless connection, disabled IPv6 by unchecking it and applying the change. Interestingly, my connection immediately dropped upon making this change in exactly the same manner as the annoying wireless drops I'm trying to fix. It did not drop the connection a minute or two earlier, when disabling the Teredo Tunneling Device driver. A restart restored my connection.</P><P>The Windows Firewall is still set to ON.</P><P>Seems to me that the common factor here is that most of the users experiencing this problem have the Intel 3945 adapter and Vista. The router does not seem to matter. Paging through the thread, the others seem to have many different routers. This problem never happened using the same wifi card and router, until I put Vista on the laptop.</P><P>I'll leave it on tonight and see if the connection drops or not.
